Aldeen, Rockford, Ill., assignor to Fyrac Manufacturing 00., Rockf poration of Illinois Application September 3, .1925, Serial No. 54,1 7 1 Renewed July 27, 1932 p 30 Claims. (01. hrs- 20)" This invention pertains to apparatus for cutting holes in glass or other material and while capable of cutting holes for various purposes, it has been designed primarily for cutting holes in 5 glass Windshields and the like of automobiles for the reception and mounting of windshield'spot lights, such as those, for instance, disclosed in Patent #1,501,704 issued July 15, 1924. The form of the invention herein illustrated and described is of the general type disclosed in my copending application, Serial No. 3,253, filed January 19, 1925 of which this application is a continuation in part.

Heretof ore, cutters for the purposes above noted comprised a large housing adapted to receive abradant, a liquid carrier for the abradant and a revoluble cutting tool around which the abradant was disposed with the housing arranged to be clamped to the material (usually sheet ma- 29 terial). This type of cutter required that the apparatus be secured to the material through which the opening was to be out before the abradant and liquid carrier could be poured into the houS- ing, otherwise the abradant would run out of the housing with the loss of the abradant and its liquid carrier and resulted in great inconvenience. The structures of most of these earlier cutters were heavy and cumbersome and no means was provided whereby abradant and its liquid could be disposed of conveniently after the opening through the glass or other material had been out In a case where an automobile windshield was being cut through, it often occurred that the abradant and liquid carrier and other debris from the cutting operation'flowed into or onto the body of the automobile, disfiguring or otherwise detrimentally affecting the parts on which it ran.

I have found that I can collect substantially all of the debris or refuse including the used abradant, its liquid carrier and the line glass particles formed during the cutting operation, and completely prevent it from falling or running onto places where it would be undesirable or detrimental. In some cases it has happened that slight leakage of abradant and liquid occurred between the cartridge shell and its nipple before or during the cutting operation, but I have discovered that this leakage also may be avoided or I rather prevented, by a simple expedient.

In the present invention therefore, one of the primary objects is to provide means whereby abradant and liquid carrier and debris formed during the cutting operation, or in other words, all refuse may be caught and prevented from flowing onto or into the vehicle or other place where it may not be desired tohave it flow. To accomplish this purpose; 'a suitable receptacle 'which'may be'used in connection with the clamptridge such as thatdisclosed in my'aforesaid co.-

pending application orforincorpora'tion inxa novel form of cartridge'to be hereinafter dis closed with which the abradant and liquidcontained in the distributed to cartridge will=be more thoroughly the edge of the cutter and the amount of leakage between the driving tool sock et or nipple and the cartridge body .will bereduced to a minimum.

A wither j ct is to provide a novel form .of- *5 1 cartridge which may be economically manufac tured and which may be refilled and used again. I

Still further objects of the invention include improvements in the cartridge holder and bracket or glass clamp, as it' may be variously termed,-

whereby the refuse receiving receptacle maybe adjustabl-y and tightlysecured against the face of I the material through which the opening isfbeing cut, opposed to the cartridge and cartridge holder;

a unique form of gasket adapted to be inter-- posed between the face of the glass adjacentthe adjustable clamp or the refuse receptacle; and a unique type of bracket which may. be economically manufactured from pressed metal upon which the cartridge holder .and clamp and the refuse receptacle may be mounted.

Many other objects and advantages will become apparent from" the description and claims and from the drawings inwhich: T

modified type of construction of I The bracket The bracket generally designated 2 is of U- shape, the legs of Which'are adapted to embrace a sheet of glass 3. The bracket is. preferably formed from two pieces of sheet metal of corresponding shape and pressed symmetrically to form right and left hand sides 4 and 5' with aifi'dge 6 thereon for the purpose of lending strength and rigidity to the assembly. The upper portions 8 and 9 of the arms of the bracket are not changed from. their original fiat state, except that the arm 8 is provided near its upperportion with outwardly pressed semi-cylindrical portions 11 and 12 on each side to form an opening which is tapped to receive an adjusting screw 13 to be hereinafter described and the-flat upper portion 9 of the other arm is formed as shown clearly in Fig. 1 and in the copending application to which reference has been made, to provide anotch l4 and a lug 16 at opposite ends of an arcuate edge 17. This latter mechanismis for the reception of thecartridge holder and its swinging yoke,

The cartridgeholder v v :The' c'artridge holderor cartridge housing as it maybe termeddesignated 18, is formed in cylindrical shape as will be seen from'l ig. 2.

It may be made by pressing sheetmetal with dies,

is provided with an opening 19 for the reception of theudriving or drivenshaft operated by an electric motor or the lik e for rotating the cutter, and with-a circumferential flange 21 about the mouththereof against thev outer face olfwhich the cutter cartridge is'adaptedto be seated and held. A strap122 engages andsubstantially sur rounds the cylindrical surface of the cartridge housing and is'securely connected thereto through the medium of outwardly pressed portions 23 of the housing engaging inopenings24 in the strap. The ends 25 and 260i the strap. are-spaced apart by means of a spacing block27 riveted thereto toforina yoke within which the upper portion Bof'the arm ofthe bracket'is received and pivot pin 28 passes through both sides'of the yoke and through a longitudinal'slot in the portionQ for longitudinal and pivotal movement of fuIlJand dotted lines in Fig.1.

the'ho'lder'between thepositions illustrated in The block 27 is formed to provide an 'abutmentlug adapted to abut against the lug 16 at one end of 'its'move mentland to be receivedwithin the slot or-recess 14. at the other end'of its movement with the cartridge holder fora. purpose to be described. On either side of the yoke-and against the exterior surfaces of the arms of the yoke, small hooks 29 are secured by means of rivets 31 which rivets also secure the blocks 2? in place to space the" arms of the yoke apart. On each side of the expanded portions of the bracket adjacent the portion 9 thereof, a rivet or abutment pin'32 is secured with E5 head spaced from the surface of thebra'cket and between these pins and the hooks 29 springs 33 are .connected. 'Thesprings 33 normally hold the lug formed on the spacer 7 2 7 within'the recess 14, b'utthrcugh the medium of the pivot pin 28 working the slot indicated in dotted lines at 10, Fig. 1, an outward pull onthe cartridge holder against the tensionof the springs 33 permits release of the lug from within the recess 14 whereupon the holder may be moved away from the'arm 8to the position'illustrated in .dottedlines in Fig. 1wher e it is held by engagement'of the lug of the spacer with the lug '16.

The return movement is effected by pushing the holder toward the arm 8, the lug formed on the spacer riding along an arcuate face of edge 15 until the springs 33 engage the spacer lug within the recess 14.

The clamp I In the above noted copending application, the cartridge or housing was illustrated and described as'adjustable, but in the present invention the cartridge holder or housing is non-adjustable with respect to the yoke band 22, and the clamp 34 is adjustable toward and from the arm 8 for the purpose of tightly securing different thicknesses of glass between it and the cartridge 35 held by the holder'or housing 18. This clamp 34, the adjustment of which is cheated by the screw 13 in the tapped hole formed by the outwardly portions 12 of the arm 8 of the bracket, is secured to the adjustment screw, by the medium of a reduced end portion 36 passing through an opening 3Z -in the back of the clamp and secured for rotation therein through the medium Ora washer 38 and a pin 39 or in any other suitable ,manner. The clamp 34 is formed in-cup-shape of abradant and fluid. carrier. for the abradant are received into the chamber orreceptacle iormed. by the diaphragm 42 and body 34 of'the clamp. For the purpose of insuring a water tight relation between thesuriace of the glass 3 against the clamp is pressed the face of'the -l"c'i kiwi agm 42,1 prefer .to secure a gasket 45 of r ient material, such as soft rubber over. a

po ion ioi" the outer face of the diaphragm 42.

This gasket is oi ylindricalorring shape and is provided with lip or flange portions iSand/MS for engagement-over the face of ,the'diaphragm s2 and springing enga geinent over-the rolled down edges thereof, respectively, and with openingsin the portion 45' corresponding to the openings and: a l in tl e diaphragm The-gasket when constructed in this manner may be removed and replaced without the use of cement or other adhesive' which is apt to deteriorate. 7 :For' the purpose of draining abradant and liquid flowing intothe receptacle or chamber in tl'ie'bod'y oi the clamp a'lowcr portion of the body of the clamp 3% which is preferably made of pressedametal; an opening is fornicdby ex truding or punching the metal outwardly 4'7. This opening is tapped to receive a spout ifi iorrnedwith a hook .9 at its upper outer end and upon this hook a sma bucket 51 is hung to receive any material d1 ing out of the chamber in the clamp. This little bucket 51 is a, part of the cutting set and has been designedito' receive the total contents from one cartridge together with any ground glass washed into the clamp receptacle after the hole has been cut through the glass.

The cartridge '7 I The cartridge: shown in Figs; 4 to *7 inclusive, -.is substantially siniilar to that describedxand claimed in the aforesaid copending application and comprises generally'a thin rnetalslriell porits purpose.

tion of cup-shape designated 52 having an outwardly projecting circumferential flange 53 about which a thin metallic diaphragm 54 is secured in watertight relation. The diaphragm 54 is preferably composed of very thin soft penetrable material such as sheet brass and. is equipped on its glass contacting face with a paper, fiber or other suitable material gasket 55 having cut away portions indicated at 56 for the purpose of reducing the amount of material to be cut away before the cutter reaches the surface of the glass.

- The gasket ispreferably composed of heavy oiled paper having a degree of compressibility .in order. to form a water tight connection between the cartridge and the glass and is secured to the diaphragm 54 with water proof cement or glue or in any other desirable manner. Before sealing the cartridge with the diaphragm 54, a nipple 57 formed of brass or any other suitable material, is tightly but revolubly inserted in a flanged opening 58 formed centrally in the back ofthe cartridge body 52 and provided with an elongated depressed portion 59 adapted to be engaged by a similarly shaped tool 61 (see Fig. 3). to be driven thereby. v

A seal of wax or other material may be placed on the interior of the cartridge betweenthe shell and the nipple to insure water tight relation of these parts, but this may be unnecessary if the nipple be made to tightly fit the opening in the sheet through which it projects. The cutter. 62 is corrugated or ribbed as at 63 to provide an irregular cutting edge with a suitable number'of openings 64 for a purpose to be hereinafter de-,

scribed and with an elongated opening 65 within which the elongated portion 59 of the nipple 57 is received. A tool 60 having a circumferential abutment 61 and a boss 61' adapted to-seat and be positioned within the nipple serves to drive the cutter when said tool is connectedto the driving shaft of an electric motor. When a suitable quantity of abradant and fluid carrier for.

the abradant has been placed within the cartridge, the cutter having been previously put in place on the nipple, the diaphragm 54 is sealed in place and the cartridge is ready for use..

In Fig. 8 I have showna modified type of con struction for the cartridge in which the parts are essentially the same as those described and shown.

in Figs. 4 to 7 inclusive with the exception that the shell 52 of the cartridge is formed with an' outwardly and backwardly flanged portion 66 on which screwthreads may be pressed'for the reception of similar threads 6'7 formed .on a ring cap 54' and whereby the destructible and removable diaphragm 55 of oiled paper or the like may be sealed or clamped to the shell and a resilient ring gasket 56 is cemented or otherwise secured tothe outer face of the ring cap 54. The

central tool and nipple receiving portion is likev The operation While it is believed that the foregoing deservtion-renders the operation of the apparatus-entirely obvious, a brief description of the manner portion 58 of the shell bucket 51 through "the spout 48.

of connecting it to the glass of a windshield and drilling the hole therethrough will be given.

'The windshield glass is preferably swung to the position shown in Fig. 1 and the bracket placed I lustrated in dotted lines. 'In this position a cartridge. is inserted and the holder swung back, to its first position where the spacer lug snaps into the depression 14. The clamp is then screwed down tightly against the glass with the spout '48 inits lowermost position. The bucket 51 is then hung on the hook49 beneath the spout and the drilling, operation is startedby inserting the tool 61 within the nipple after it..has been connected to the driving shaft of an electric motor or other prime mover; V

Rotation of .-the tool will rotate the nipple 57 Within the projecting portion 58 and thereby the cutter, which, after cutting through the jtlia-v phragm and connecting portions of the center i and the rim of the gasket 55, operates on the glass,

drives the abradant thereagainstand gradually cuts the hole there'through. The openings 64 perof the cutterand, in fact, under centrifugal action of the cuttenit appears that some suction action takes place betweenthe front and back of the'cutter due to these openings which pulls any liquid and abradant tending to. accumulate behind the center of the cutter into the interior of thecutter. ,Whatever the principle of the operation, the result is, that leakage tending to occur between the nipple and the outwardly flanged is minimized or entirely eliminated.

' As soon as the cutter has penetrated the glass,

the liquid carrier and abradant seep or flow through the cut in the glass into the chamber formed in the clamp and therefrom into the This prevents the hard particles of abradant, ground glassand water from flowing onto the automobile or other vehicle or place utilizing the glass through which the hole is being ,cut. The cutter is stopped. as soon as the hole has .been cut through the glass to prevent its cutting through'the rubber 46 and the bracket is removed from the glassand the used cartridge and cutter thrown away or re- .cilitates construction while producing a simple but strong structure which can be manufac The apparatus is supplied to each spotlight dealer or otherperson who may desire to utilize the apparatus tured at low cost for its purposes.
